Top quark mass effects in Higgs boson pair production at the LHC — •Jonathan Grigo¹, Jens Hoff¹, Kirill Melnikov², and Matthias Steinhauser¹ — ¹Karlsruhe Institute of Technology, Karlsruhe, Germany — ²Johns Hopkins University, Baltimore, MD, USA

Higgs boson pair production is considered at next-to-leading order in QCD in the Standard Model. We compute the total cross section, including corrections of inverse powers of the top quark mass which turn out to be numerically important. We discuss their relevance for the determination of the triple Higgs coupling.
